i BELT FASTENER.

vide simple means which will permit the' belt to be attached to therestraining device without the'necessity of dismantling it for suchattachment.

A further object of the invention is to provide attaching means thatwill enable the motor vehicle owner Yto install new belts without thenecessity of detaching the restraining device from the vehicle.

A still further object ofthe invention is to provide fastening meanswhich will serve as a protecting shield for the upper end portion of thebelt where it is secured to the restraining device. Y

Still a further object of the invention is to provide simple lockingmeans whereby the fastener can be securely locked in operative position.l

Still another object of the invention is to provide means by which thebelt can be attached and detached to and from the device without the useof bolts, nuts, rivets, etc.

lfiith these and other objects in view, the invention consists of theconstruction, combination and'arrangement of parts hereinafter morefully described, claimed and illustrated in the accompanying drawings inwhich like ordinals or reference characters indicate like parts thruoutthe several figures of whichy Figure 1 is a side elevation representinga fragment of a vehicle and illustrates a one way acting restrainingdevice mounted thereon. Fig. 2 is an enlarged side elevation of therestraining device shown in Fig. 1 and is shown with the cover removedand fragments broken away andshown in section.

Fig. 3 is an end elevation of Fig. 2, shownV partlyv in section, andtaken approximately on the line 3-3 in Fig. 2. Fig. 4 is an enlargedperspective view of the upper clamp plate and Fig. 5 an enlargedperspective view of the lower clamp plate. Fig. 6 is an enlarged view ofthe belt anchor plate and Fig. 7 is a longitudinal sectionof thecomplete fastener illustrating a fragment of the belt in place.

rReferring to the drawings, 2 represents a vehicle frame, 4 a vehiclemainY spring connected to the frame and 6 an axle supporting the spring.10 represents a hub support by means of which the restraining de- Vviceis mounted on the frame 2 and is secured thereto by means of a securingbolt 18 and a nut 15. 10-represents an outwardly disposed lug or stopwhich is adapted to engage against the lower flange of the frame member2 and thereby prevents independent rotation of the rebound check unitwhen secured in position on thev frame. 10b represents an expandedcircular flanged portion which forms a cover for one side of the de viceand upon whichv a friction disk 14 is non-rotatably mounted.

18 represents a plurality of dowel pins, one only of which isillustratedythese pins servek to mount the friction disk 14 on theflanged portion l0b and also serve to prevent rotation of the frictiondisk thereon. 20 represents a conical friction cup which engages withthe friction disk 14.

The 'friction cup 2O is non-rotatably mounted on a pair of hollowcircular cupped shaped members 24 and 25' respectively, by means' of' arivet 27. The members 24 and 25 are provided with flat circulardiskportions 24@l and 25 respectively, each of which blendV into outwardlydisposed circular flange portions 24b and 25h respectively, Vforming acylindrical drum. The disk portions 24a and 25at are arranged adiacentone another and are secured together also by rivet Q7. y The disks 24nand 252L have provided in their central portions circular apertures 24and 25".

10' represents a. cylindrical hub portion which is .iorizontallydisposed from tbe cel. tral ange or disk 10b of thesupporting member10.y The hub is provided with a plurality of grooves 10d.

40 represents aV cap screw which engages in a hollow threaded portion10e provided in the horizontal axis of the hub 10c. 42 represents a coilcompression spring which exerts apressure against a pressure plate 43 atone extremity and against a cupped*l shaped adapter 45 at the otherextremity. ri'fhe pressure plate 43 exerts a pressure against a thrustbearing' 44. The adapter 45 is provided with pins 46 which engage in thegrooves l0d and prevent rotation thereon. The cap screw 40, togetherwith a Hat washer 47, holds the adapter 45 in place against the end ofthe hub 10.

The pressure exerted by the spring 42 forces the cup 2() against thedisk 14 which sets up friction between th-e parts when the cup 2() isoscillated. represents a spiral spring which is anchored at its outere2;- tremity to the drum or cup 25 by means of an anchor plate 33. lt isanchored at its inner extremity to the adapter 45 by means of a lippedportion 32 The lipped portion engages in a slot 45 provided in theadapter The parts thus far described can repre" sent any conventionaltype of one way restrainingl device, and this particular form isemployed only for the purpose of clearly illustrating` my invention. Theoperation of these devices when applied to motor vehicles, are wellknown to those skilled in the art.

50 represents a flexible connecting belt which is secured to the axlebracket 5l, the bracket being anchored to the axle 6. My new fastenerwhich is illustrated in the present instance for securing the upper eX-tremity of the belt 50 to the restraining device will be described asfollows:

55 is an anchor plate which is, in the present instance, secured to thecircular cupped shaped members 24 and 25 by means of a pocket portion 56formed in the disks 24 and 25. lt is secured therein by means of rivets57-57 which are inserted in apertures 55 in the anchor plate The upperextremity of the anchor plate is provided with an aperture 55 which, forthe purpose of illustration, is located in the central part thereof. i

56 represents a lower clamp plate which conforms to, and lies adjacentthe outer periphery of the circular flanges 24" and 25b respectively.The lower clamp plate is provided with a central rectangular slot 58 andwith four apertures 5S. 60 represents an upper clamp plate and is alsoprovided with a rectangular' slot 60 and with four apertures 60h. Theupper clamp plate 60 has a `downwardly dispos-ed flanged portion, 60(lat one extremity, and a hollow embossed or shroud portion 60 in thecenter portion thereof, thc hollow portion arranged to mate with theaperture 55b in the anchor plate 55. l

The belt 50 is interposed between the upper and lower clamp plates andis secured in position in the present instance, by means of `a pluralityof rivets 52 which are inserted in the apertures 55 and 60brespectively. The slots in the upper and lower plate align with eachother when assembled together. To permit the protrud-ed portion of theanchor plate 55 to pass thru the slots 58 and 60, a similar slot 50 isprovided in the belt 50. A cotter pin 62 is inserted thru the shroud 60eand thru the aperture 55b for locking the belt fastener in position onthe drum.

When the fastener is in operative position on a vehicle, it will be seenthat the pull exerted by the torsion or spiral spring in therestraining` device will keep a constant tension on the belt whichaction will tend to pull the fastener snugly against the drum.

The upper and lower clamp plates of the fastener serve to protect thebelt as they are usually made of metal or a material much tougher andharder than that of which th-e belt is mad-e. The pulling strainsexerted by the belt are transmitted directly to the clamp plates as thebelt fastener will shift on the drum, when a pull is exerted by thebelt7 until Contact is gained at one extreniityV of the slots 58 and 60against the anchor plate 55 which then acts as a driving member tooscillate the drum.

The restraining device when installed on a vehicle is set in such aposition that the eXtreme range of travel of the belt will not changethe direction of pull on the fastener so that it would tend to lift itolf of the drum. Locating the faste erposition on the restraining devicewhen making installations on the vehicles, permits the use of a Cotterpin as a locking medium which only serves to prevent the fastener fromlifting off the anchor plate, atendency which would be caused by quickvibrations. Since there is a constant tension on the belt when inoperative position, there is no slipping tendency of the fastener on thedrum.

The flanged end 66 on the upper clamp plate 60 protects the extreme endof the belt from wear or fraying, and provides a smooth rounded cornerfor the belt to wind on if the travel of restraining device becomesgreat enough to cause the belt to wind conipletely around the drum..

It is thus seen that the invention provides a simple compact and durableconstruction requiring but comparatively few parts; one which will noteasily get out of order: one which can be made of pressed steelstampings; and one in which a very small amount of wear should occur.

lWhile I have illustrated and described with particular-ity, onepreferred form of my invention, I do not desire to be limited to theexact structural details thus illustrated and described; but intend tocover all forms and arrangements which come. within the terms employedin the definition of my invention constituting the appended claims.
